Four Worlds
The Four Worlds (Hebrew: עולמות ʿOlāmot, singular: ʿOlām עולם), sometimes counted with a primordial world, Adam Kadmon, and called the Five Worlds, are the comprehensive categories of spiritual realms in Lurianic Kabbalah in a descending chain of existence. The concept of "Worlds" denotes the emanation of creative lifeforce from the Ein Sof or Godhead through progressive, innumerable tzimtzumim or concealments.
